Very useful info, but one suggestion:

At the top of the PoserPython forum there is a notice saying:

You can now attach text files to your posts to pass around scripts. Just attach the script as a txt file like you would a jpg or gif. Since the forum will use a random name for the file in the link, you should give instructions on what the file name should be and where to install it. Its a good idea to usually put that info right in the script file as well.

I assume this works also for Poser content files.
